LTR Programming:
1. In the LS Trunking Personality window, check the Option Board Feature box for each personality. Check the
Option Board Feature
box for all channels if using a button to control the mode of the scrambler. If doing
scrambling on a per channel basis, then check Option Board Feature only for scrambled channels. It will be
necessary to set the power up state of the scrambler to Scramble for per channel scrambling.
2. In the LS Trunking Site window Pre-Emphasis should be enabled, but De-Emphasis must not be enabled.
This is because De-Emphasis will prevent the scrambler from decoding synchronization data. The scrambler
by its very nature performs De-Emphasis function. Compression should not be used with the scrambler.
Expansion should also be disabled.
